Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles. It was among the first units with manufacturer-customizable fuel delivery maps which used rpm, throttle position, temperature, and sometimes barometric pressure as inputs. This was accomplished mechanically, not electronically, using cones (irregularly shaped, two-dimensional cams) to encode the maps.

Due to high manufacturing cost however, it became economically undesirable with the introduction of cheaper electronic engine management systems (and continuous-injection mechanical systems) by the end of the decade. However, the Kugelfischer system continued to be used as a specialty injection pump for purpose-built race engines into the 1980s such as the 1982 Porsche 911 SC/RS.
